Example Setpoint Calculations
The following tables show how to apply the formulas from the
preceding section. Each mode (Occupied, Unoccupied, or
Standby) uses the default values shown in Table 29. Table 30
provides common setpoint scenarios as a helpful reference
when working with temperature setpoint parameters. Table
31 shows which WSHP models apply to each unit type
(HP0-HP3).
Table 29: Temperature Setpoint Defaults
AV1 (nciSetpoints.occupied_cool) =
75°F
AV5 (nciSetpoints.standby_heat) =
66°F
AV2 (nciSetpoints.standby_cool) =
77°F
AV6 (nciSetpoints.unoccupied_heat)
= 60°F
AV3 (nciSetpoints.unoccupied_cool)
= 85°F
AV10 (nciOccDiff) = 1°F
AV4 (nciSetpoints.occupied_heat) =
70°F
AV17 (uciUnoccDiff) = 2°F
